This paper discussed a comparative study of several state-of-art methods for determining building energy consumption benchmark. A new approach, which combined the idea of ＂building benchmark＂ and ＂operational benchmark＂ in its rating system, was proposed. A case study was conducted which applied the proposed approach to benchmarking an existing office building in Tianjin. Besides, the calculation of benchmarks of the reference building model and real building model using the rating method in eQUEST was also considered. Furthermore, the simulation results of the reference building model were taken as the baseline to divide real office buildings into different energy performance grades.

SlZF3 regulates tomato plant height by directly repressing SlGA20ox4 in the gibberellic acid biosynthesis pathway

第25届中国控制与决策会议

作者： Zhang Qingxin yu huiyang Xie yuhuan School of Automation Shenyang Aerospace University

ISBN: (纸本)9781467355339

A mobile robot perceptual system is designed in this paper. We can get the robot’s position not only by sensors but also by wireless location based on the Received Signal Strength Indicator （RSSI）. A test platform can be provided for the study on formation control and dynamic positioning of multiple mobile robots. In addition a method and algorithm of location problem is proposed. The location problem is transformed into a nonlinear optimization by the optimization algorithm proposed in this paper. The optimal design of parameters is processed by using the Broyden-Flether-Goldfarb-Shanno（BFGS） method of variable metric method, penalty function method and the line-search method. The calculating methods are implemented by program of MATLAB and Visual C++. The simulation results show that this method is correct and effective, which have high location accuracy, low computational complex, perfect stability and fast convergence speed.

地球是一种物质和能量结合的存在形式。地球及其他行星的形成和运作过程实际上是物质和能量状态的演化历史。研究物质的科学是物理和化学,描述物质自然规律的语言是数学,这属于热力学的研究范畴。从19世纪中叶开尔文利用热力学理论计算地球年龄开始,热力学在地球科学领域的应用已有100多年历史,它在阐释地球和行星演化过程的基本逻辑与规律方面发挥了核心作用,引起了固体地球科学发展史中的许多重要变革。近20年来,随着物理、化学和计算机科学的不断发展,经典热力学和非平衡热力学在地球物质科学中的应用进一步发展,成为地球物质研究的基本原理体系。通过研究地球物质的形成与演化条件来揭示地球结构、动力学和演化过程的地球热力学学科已经形成。未来地球热力学的发展需要与地球物理、地球化学理论和实验相结合,在热力学数据库发展的基础上,建立合适的热力学模型来解决实际的地球科学问题。另外,地球热力学的进一步发展需要与相应的课程教学相结合、加强热力学在地球科学中的课程建设是当前的一项重要任务。热力学是地球物理、地球化学、地质学等多学科交叉研究的纽带和桥梁。如何从热力学的视角认识地球及其演变过程将会是一个永恒课题。
